Hi reader, how are you ? :) - Great, me too, thx for asking. Listen i heard about optimizer named CCleaner, i visited the main page of the software, and got myself surprised a lot. Over 185 million downloads!!! wow that's a LOT for a FREE software. So i decided to give it a try. So follow up The install process is fast, and gives customization options, like removing toolbar from install process, that's a plus, if you don't like to install it. Some other programs forces you to install it, or they hide it in the install process, so you don't notice and install it after all. Here's a screen from the program main window - The first look felt good. Why ? Well you can see 4 main futures that a lot of expensive programs don't have: - Cleaner for Windows Operating system - Cleaner for Applications in Windows ( Automatically loads all applications from your system, and gives you option for deleting their temporary files - the ones that slow down your system_ - Registry Cleaner - hmm goodie - Tools - Uninstall and Start Up Maganer Let me remind you that this program is FREE for use once again, and it has 4+ futures that you would pay a lot $$ for them with other programs Ok, i tested the windows clean option, it worked perfectly, deleted about 420mb of temporary files, then i thought damn, i'm screwed that's for sure (that was 6 hours ago) and none of the files I use, or i need is not deleted,only temporary and that was Fast. I can really tell that I fell Big diffrence in system speed. Important: If you have a lot passwords stored in your cookies, don't chech that box, you will need to relog on theese sites ( forums, etc...) Registry Cleaner - the most important in windows speed improving factor Nothing is more important than clean registry - windows have all the infos for system working saved here, the hdd space used for programs is only for them, and doesn't have any influence in windows working speed. Uninstall and Start Up manager is something i didn't use, i have all of them sorted up before, but as far as i can see from other reviews - works like a charm. So bottom line about CCleaner - Piriform did an excelent job with this software. Works like a charm, and PC speed improving is definilty noticable Doesn't have some futures like some other softwares, but concidering it's free, that's not big minus here. It's free of charge, no need to wait - download it and feel the diffrence ;) Publisher description CCleaner is a freeware system optimization, privacy and cleaning tool.
